2 6 Claims. (CI. 20-53 This invention relates to a device for holdingthe lower edge of a storm sash or the like.

An object of this invention is to provide a readily operated devicewhich can hold the lower edge of a storm sash'open or closed.

A further object of this invention is to provide a sash holder whichincludes an elongated main arm pivotally mounted on the sash which canswing between an open position in which the elongated arm engages a studmember which is attached to the casing of the window and holds the sashopen and a closed position in which a track on the elongated memberadjacent the pivot thereof engages and grips the stud to hold the sashclosed.

The above and other objects and features of this invention will in partbe apparent and in part be obvious to those skilled in the art to whichthis invention pertains from the following detailed description, and thedrawing, in which:

- Fig. 9 is a fragmentary view in horizontal section showing a screenequipped with a similar device.

In the following detailed description, and the drawing, like referencecharacters indicate like parts.

In Figs. 1 and 2 is shown a window opening 10 provided with a casinghaving side members 12 and 14, a stool 16, and a lintel 15. Upper andlower sash are indicated at 17 and 18, respectively. The upper and lowersash run in channels 19 and 21 in the usual manner. The outer guides forthe track of the upper sash are formed by molding strips 22 and 23 whichare ordinarily referred to as blind stops. A storm sash 24 having aglass sheet 25 is hinged to the lintel by hinges 26. The storm sash maybe held in open position, as shown in Figs. 1 and 2 by sash-holdingdevices indicated at 27 and 28.

Details of construction of one of the sash-holding debe used inconnectio n rwith a window Patented June 2, 1959 vices are shown inFigs. 3 to 8 inclusive. As shown most clearly in Figs. 4 and 5, thesash-holding device 27 includes an elongated main arm 29 which ispivotally mounted on a hinge plate 31 by a pivot 32 (see Figs; 3 and 4)adjacent one end of the arm 29. The hinge plate 31, in turn, ispivotally attached to another hinge plate 33 by a pivot pin 34. Theplate 33 is rigidly attached to a side frame member 36 of the storm sash24. As shown, the arm 29-swings about its pivot32 in a plane parallel tothe hinge plate 31.

When the storm sash is in open position, the arm 29 engages a studmember or screw 37 having an enlarged head. The stud or screw 37extendsinto the blind stop 22, 'as shown most clearly in Figs. 3 and 7. Whenthe storm sash is open, the head of the stud 37 is received in a bayonetslot 38 adjacent the free end of the main arm of the device. A catch41,- which is pivotally attached to the main arm, is provided withradial grooves 42 one of which receives the stud member 37 to hold thearm in place with the shank of the stud member in the narrow portion ofthe bayonet slot.

When the storm sash is to be closed, the'catch 41 is swung away torelease the stud member 37. An inwardly directed flange 43 on the mainarm can be grasped to swing the main arm inwardly to the position 'shownin dotted lines in Fig. 2 at which the main arm is released from thestud member. The main aim of the device 27 may be released in a similarmanner. Then the storm sash is drawn to theclosed position indicated'in'Figs. 3, 4 and 5. As shown in Fig. 1, the distance of the stud memberfrom the lintel is equal to the'distance from the upper edge of thestorm sash to the pivot 32 of arm 29 so that, when the storm sash isclosed, the pivot 32 and the stud member 37 are in registry; A trackcomprising angle-shaped flanges 44 and 45 is mounted on one side of themain arm in registry withthe pivotthereof. The flanges 44 and 45 arespaced to provide a slot 46 therebetween. When the sash is drawn to theposition shown in Fig. 8, the flanges 44 and 45 register with the screw37 and the screw is received in the slot 46 between the flanges with thescrew head being in registry. with the pivot of the main arm 29. Asshown, the width of'the slot 46 is greater than the diameter of theshank of the stud member, but less than the diameter of the head thereofso that the stud member is held thereby. Then the arm may be swungdownwardly to the position shown in Figs. 3, 4 and 5 in which thesash-is latched closed. As the arm swings, the flanges of the trackswing therewith to the Fig. 5 position at which the flange 45 can engagethe stud member 37 to hold the storm sash closed. As shown in Fig.- 6,when themain arm is swung down to this position, the main arm is inalignment with the blind stop 22. As shown, the main arm is narrowerthan the blind stop so that the device does not interfere with operationof the Window sash. As, shownmost clearly in Figs. ,3 and 4, the hingeplate 33 is attached to the frame of the storm sas'h in alignment withthe track flanges 44 and 45 so that a minimum amount of space is takenup by the sash holding device. I

The device has been described to this point with relation to a stormsash; however, a similar device may screen. In Fig. 9, a device 47 isshown; If de'sired,"hinge plates 49 (only one of which is shown) may beattached to the sides of the screen frame. These hinge plates 49 may beidentical in construction with those attached to the storm sash so that,when the hinge pins are withdrawn, the main arms and associated parts ofthe devices may be used both with a storm sash and with a screen.

The devices described above and illustrated in the drawing are subjectto structural modification without departing from the spirit and scopeof the appended claims,
